    • Abstract
  • In recent years, with the development of computer technology and numerical theory of geotechnical engineering, numerical simulation analysis is more and more applied in geotechnical engineering. Based on a deep foundation pit in Qingdao, the geotechnical finite element soft PLAXIS is used to simulate the whole process of double-row piles. The change trend of horizontal displacement is analyzed and compared with the measured data. At the same time the single-row pile supporting method is compared and analyzed, the double-row piles are proved to have obvious advantages in restricting the horizontal displacement. Therefore, the numerical simulation may provide effective help for selection of supporting methods and stability analysis of foundation pits.
